Re: Guitalele / Martin 5 Terz

I use 45mm width at the nut and 53mm on centre to string spacing at the saddle. I did one out at 50mm at the nut and I think from memory it was 56mm at the saddle for a client that was coming from Classical Guitar and he liked it but I thought it was way too wide for my liking, and it just looked re...

Re: Guitalele / Martin 5 Terz

I've built several Guitalele's on both the tenor and baritone body size. The more traditional one is on the tenor but I think the baritone size with a 21.5" scale suits the tuning of A-a better. All my necks get a CF truss rod no matter the size of the instrument. I use Requinto strings or alternate...

Re: Updated Epoxy Pore Filling Demo - Video

I never leave a "layer" of epoxy. But it's a fine line of sanding so you are just leaving it in the pores or cutting timber off and exposing more pores.

Re: Updated Epoxy Pore Filling Demo - Video

Same for for all subsiquent coats as required.

For softwood soundboards that don't get pore filled I will sand up to P320 with my Festool fine orbit sander. It gives an effective finish as if you were going P400 by hand.

Re: Leveling dust specs and other imperfections

It depends on what finish you are using as to what you can go with for sanding grit. Some requite no more than P400 for a good bond. Others can be up at P800 and still work out fine. Just depends on that particular finish. Many used in the automotive trade require P600 to P800 and nothing coarser or...

Re: Baritone Ukulele

If you have used a fan bracing pattern and there are "dips" between them, then my experience is that you have taken the top just a bit too thin. I had this problem on earlier instruments until I tried going with slightly heavier soundboard and lighter bracing. I'm not sure what you are refering to i...

Re: Sanding Sealer

I use the 2K Polyurethane sanding sealer in the system I'm finishing with. All finishes are speced to be sprayed at 20C to achieve the correct viscosity per their reducer / thinner recomondations. If it's still too thick for your liking then warming it up even more certainly will help with spraying ...

Re: Sanding Sealer

If you are going for a high gloss and perfect finish, then your pore filling / sealing has to be pretty much perfect before you proceed onto your top coats. Most people are far too impatient and jump ahead before getting this critical step done. There are lots of methods to prep that timber. I've tr...

Re: Side waves

I had some Blackwood that would do that no matter what I did while bending. Sometimes wood will just do what it wants to do and we have to either walk away from using it, or learn to live with it. If you are going forward with it as is then using a low gloss / satin finish will help disguise the wav...

If you are using pumice with the shellac then you can get very good results. Though it is very time consuming. It's the first step in a full French Polish finish. The pumic is inert and the shellac binds it. You still need to leave an appropriate amount of dry time to get the alcohol fully evaporate...

In deep pores using this method you are going to experience some serious sink back down the road as the lacquer continues to dry. And that process of drying / shrinking never stops with a solvent based lacquer. That's why when builders are serious about dead flat and high gloss finishes that last th...

Re: Alternatives to Mirotone for clear hi gloss finish

The Gold Standard would be Mirothane Polyurethane. But you'll be up for even more than Mirotone lacquer. It's also much more difficult to spray unless you are competent with a gun.

You will be very hard pressed to find a harder, yet more flexible finish.

If your sides are the same depth at tall block and neck then your uke is going to look pretty strange. They should taper in body depth from deepest at tail block to the neck.
